Application filed May 11. 1906. Serial No. 316,398.

To all whom, ft 71pm/ concern:

Be it known that I, SOLOMON M. KEMP, a citizen of the United States,residing at Baltimore city, State of Maryland, have invented certain newand useful Improvements -in Chimneys, of which the following is aspeciiication. 4

My invention relates to an improvement in chimneys, the Object being toprovide a cheap, durable and effective chimney, that can be quicklyinstalled whenever it is found necessary to replace a chimney by way ofrepair, but, more especially to be used in the iirst construction wherea chimney is necessitated or desired.

It is a Well known fact that the decay of an ordinary chimneyconstructed of brick and mortar is to a great extent caused by the gaseswhich necessarily pass through it, which destroy Athe mortar and causethe chimney to crumble and fall, necessitating` the restoration of thechimney as originally built or to provide a substitute of some kind ordescription.

By the use of my invention in such cases a chimney can be substituted ata comparatively less cost and inconvenience. By the original adoptionand construction of my chimney, it in all cases of original building,where chimneys are used, will result in a saving of cost'eii'ected bythe durability thereof over and above that of an ordinary chimneycomposed of brick and mortar. Being composed of concrete, or othersuitable material the chimney is not affected by the gaseswhich passthrough it, and the reinforcement (woven wire) used in the constructionthereof, being molded within it,

prevents it from crumbling and falling.

It also consists in certair other new and novel features of constructionand combinations oi parts, which will be hereinafter described andpointed out in the claims.

In the accompanying drawings Figure 1 is a perspective view of myinvention. Figs. 2, 3, 4, 5 and 6 are perspective views of differentparts or blocks of the chimney with parts broken away to show the wirerein forcement and lue board.

In Fig. 2, A is a top section constructed of concrete or other suitablematerial. 1 1 are extensions of two side walls of the top section intowhich the chimney cap or top B is fitted, the lower edge ends of the capresting on the top of the walls 2 Vat 3; 4 is a groove into which theiiashing of the roof 5 is secured; 6 represents the reinforcement (wovenwire) molded within the concrete. The several sections forming thechimney have the side walls 2 cut away at their lower end portionsthereby allowing the lower ends of the walls 1-1 to extend beyond thelower ends tensions 12 forming a mortise joint, adapted to be fitted tothe tenon or extension 7 as shown in Fig. 2, and is likewise providedwith a similar tenon or extension 7 on its lower end portion as are allother sections, except the bottom or ground section F as shown in Fig.6. Likewise are all the other sections constructed so as to be providedwith the shoulder 11, and the extension 12 forming a mortise joint, asshown in Fig. 3 for the purpose of engaging with the tenon or extension7 of the adjacent section.

In Fig. 4. D, is an elbow section provided with a similar openingtherein as shown in Fig. 3 for the purpose of having a register fittedtherein, which we will also designate 8. This elbow is molded to form anangle of any number of degrees as is the section E, that they may meetand the extension or tenon 7 on that of section D, may be engaged by theextension 12 and shoulder 11, forming a mortise joint of section E.These forms of angle sections are for the purpose of extending andcontinuing the chimney from a given point to another point, where otherconnection with heating apparatus may be desired, or for the purpose ofdistributing heat to other parts of the building, thus providing againstthe necessity of an additional chimney. tion, and 13 is a door which isremovably secured to the section by means of the'bolts 14 (which aremolded within the side walls 1) and the nuts 15, said door having therequisite number of holes molded or drilled therein at the properlocations to allow the IOO F is thiI` bottom secbolts to extendtherethrough that it may be v secured in the manner as above stated. 16is an opening in the door through which the TIO smoke pipe (not shown)may be inserted. The door is made removable to facilitate the cleaningof the chimney or the repairing or restoring the smoke pipe whennecessary. In installin@r my chimney, section F being the lowerorbbottom section, is placed in position.

and around the mortise joint formed by the extension 12 and shoulder 11is spread a thin layer of concrete, the next section provided with tenonor extension 7 is then fitted upon the top thereof and in like mannerthe succeeding sections either straight sections or those of elbowJformation, as may be desired are fitted together in a similar mannerand by similar means. When the concrete dries and hardens, the chimneybecomes solidly secured together as if composed of one continuoussection of concrete.

While I have shown the lower end portion of the several sections, cutaway so'as to form the tenon or projection 7 on but two sides, andlikewise the upper end ortions cut away on but two sides so as to ormthe shoulder 11 and the extension 12, forming a mortise joint, yet it isvery apparent that the upper ends of the several sectio'ns might be cutaway on all four sides to the extent of one-half the thickness thereof7that the extension 12 as shown might extend around all four sidesthereof and likewise the inner lower end ortions might be cut away onehalf the thickness thereof on all four sides thereof, instead of as inthe manner as shown and the same result will be had, hence I do notdesire to limit myself to the exact construction as herein set forth, asI am aware that slight changes might be resorted to in the form andarrangement of the several parts withoutdeparting from the spirit andscope of my invention.

Having fully described my invention, what I claim as new and desire tosecure by Letters Patent isz- 1. The combination of a chimney cap and achimney substantially as hereinbefore described, comprising a sectionmade of concrete, of a woven wire reinforcement molded within the wallsthereof, of extensions or tenons on the lower end portion, of lsimilarextensions on the opposite end or upper portion thereof, the upperextensions affording a means for securing the cap on the section for thepurpose as herein set forth.

2. The combination of a chimney substantially as hereinbefore described,comprising a base or lower section made of concrete and provided withwoven wire molded within the walls thereof, and an extension andshoulder forming a mortise joint o`n the top end portion, of a series ofmetal bolts secured within the edges of the parallel side walls andthreaded on the extended end portions thereof, and a door provided withan opening therein and means within the door for allowing the extendedend portions of the bolts to pass therethrough whereby by the means of aseries of nuts the door is removably secured to the said base or sectionfor the purpose as herein set forth.

In testimony whereof I aflix my signature in presence of two witnesses.
